To oir/ZZ whom it' may concern:

Beit knownthat we,-GRORGEW. GUMNooK and FRED E. WARREN, citizens of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have 'invented new and useful Improvements in Looms for `Weaving -Bo'rdered Fabrics, of which the following is a specification.`

Our invention relates to looms, and'contemplates the provision of a plainA loom with sim` ple,easyoperating,`and efficient means whereby the harness maybe caused to run and vdwell at predetermined times toput in tape effects and the cloth-rollmay be stopped and the harness caused to dwell at suitable intervals toform what `is known as the cord i effect. y

The invention is designed more particularly for weaving borders and fancy designs upon cotton, woolen,and'otl1`er fabrics, and it will be fully understood from the following description and claims when takenin conjuncloom. Fig. 5 is a transverse section of the Q tion with' the accompanying drawings, in which- Y Figure lis an end elevation of a plain loom equipped with our improvements. Fig. 2 is adetail frontvview of a portion of the loom.

Fig. 6 is detail horizontal section illustrativeof the manner in which the arm of the pawl for transmitting motion to the pattern-shaft is engaged by the tappet to disen- `gage the pawl and renderthe pattern-shaft idle. Fig. 7 is a detail View of a portion ofthe pattern-chain and finger designed to be' engaged by certain. tappets or rolls thereof. Fig.y 8 is a diagrammatic view illustrative of the arrangement of dthe tappets of thepattern.

the vpattern-chain shaft,.a bell-crank lever-c,v loose `on said shaft and carrying a pawl d, and a rode, connecting a crankfonthe cam-shaft and the lever c. These parts may allbe of thev two sheds incidenttotwo revolutions of the Loosely mounted on thel cam-shaft Cy is al the treadles G, and splined onthegsame shaft` 3, and 4.. This clutch-controllingmechanismcomprises alever N for shipping thespleeve; i J in and out of engagement-with the cani-hul)` L, a bell-crank lever P, a pitma'n Q,`c` ,c` nnect1` ing the bell-crank lever and the lever N, aA .1

`6o l other suitable construction, and whendesired n l g l v 6,5 When the parts are ofthe construction com i mon `tol plain looms,-it.follows that thecam* v `75 .i clutch-face on the hnb J, whereby it will be i with the hub J the cams will lturn with the p shaftand the harness will be actuated, while From this 'it follows thatfy the:l sleeve L may with proprietybe broadly do-V the pattern-chain and sleeve Lthecontr0l-l v ICO and having its opposite end bifureated and connected to the. lingers S S, as best shown in Fig. 4. By reason of this construction when either one of the fingers or finger-levers S S is engaged and raised by a tappet of the pattern-chain the sleeve L will be disengaged from the cam-hub J, and in consequence said cam-hub and the harness which gains its motion from the cams thereon will be caused to dwell. The du ration of the dwell of the harness corresponds to the length of time the finger S or S is held in :its raised position, and when the finger is released the spring R will throw the sleeve L into engagement with the cam-hub J and the operation ofthe harness will be resumed. The fingers S S are of different shapes, so that one will remain in engagement with and be held in its raised position by the respective tappets of the pattern-chain when said chain is in motion longer than the other will remain in engagement with and be held inits raised position by its respective tappets of the moving pattern-chain. For instance, the finger S is so shaped that a tappet on the pattern-chain followed by an empty bar will in passing beneath it keep it raised and the sleeve L out ot' engagement with the cam -hub J stifliciently long to enable the loom to weave a number of picksmsayfour-in one shed, and the finger S is so shaped, as shown in Fig. 7, that a tappet on the pattern-chain followed b v an empty bar 'will in passing beneath it keep it raised and the sleeve L disengaged from the hub J long enough to enable the loom to weave a less number of pickssay two-dn one shed. The fingers S S'are never simultaneously raised by tappets of the pattern-chain, and hence a single rod T with a bifurcated upper end may be employed to connect the two fingers with the bell-crank lever P in the manner described.

Connected by suitable gearing with the cloth-roll l-I, as best shown in Fig. 5, is a shaft U, bearing the take-up ratchet-wheel V, in conjunction with which ratchet-wheel the usual actuatingipawl W and gravitating pawl X are employed. The pawl X has a toe a3 to engage the teeth of the ratchet-wheel V and is provided adjacent to its rear end with a slot a, which receives a stud c5 on the frame A. At its upper side said pawl X has teeth a, which are designed for the engagement of a pawl d, pivotally mounted on the stud a5. rlhis latter pawl a is looselyconnected to an arm a8, iixed on a rock-shaft a7. The pawl X, pawl d, and arm as are of the ordinary construction, and the shaft a7, carrying the said arm as, is designed to be connected in the usual manner with the well-known threadcontrolled mechanism. (Not shown.) The pawl a normally engages a tooth of pawl X, and thereby holds said pawl X against endwise movement and enables it when in engagement with the wheel V to hold said wheel against retrograde movement. In the event of the thread breaking the thread-controlled mechanism l(not shown) operates in the usual manner to raise the pawl o. out of engagement with pawl X and permits said pawl X to slide back, which results in a stoppage of the taking up of the cloth on roll Il. When the thread is mended, the thread-controlling mechanism is returned to its normal position and the pawl a6 is rengaged with a tooth of the pawl X.

The pawl X is connected by a rod Y with a finger Z, which is arranged to be engaged by certain tappets of the pattern-chain.

The actuating-pawl W moves the wheel V the distance of one tooth in the direction ot` the arrow in Fig. l incident to each rotation of the cam-shaft C, and the pawl X in the position shown holds the wheel against retrograde movement. The cloth-roll H being eonnected by gearing with the wheel Vis turned in the direction indicated by arrow and takes up the cloth thereon. When, however, the pawl X is raised out of engagement with the teeth of wheel V, the operating-pawl W, while continuing to reciprocate, will remain in engagement with a single tooth and will not turn the wheel V and the cloth-roll in the direction indicated. This is due to the fact that when the pawl X is disengaged from the teeth of wheel V the tension of the cloth acts to turn the roll H in the direction opposite to that indicated by arrow and causes the ratchet-wheel V to move back with each rearward stroke ot' the operating-pawl W, with the result that said pawl W remains in cngagement with a single tooth of said wheel and is not able to rotate the same in a forward direction. i

It will be seen from the foregoing that the pawl X constitutes and may with propriety be broadly denominated a elotl1-1'oll stopmotion device.

The position of the pawl X with respect to the ratehetewheel V is controlled by the iinger Z with which the pawl is connected, as stated, and the pattern-chain. The fingerZ is shaped like the finger S, and tappets are arranged on the pattern-chain to simultaneously engage and raise the said fingers. It follows from this that the elevation of the finger S and the stoppage of the harness caused thereby will correspond in duration to the elevation of the iinger Z and the suspension of the taking up of the cloth resulting therefrom.

For the purpose of governing the stop-motion to the pattern -chain shaft a linger A', which is arranged to be engaged by tappets of the pattern-chain, is employed in conjunction with a bell-crank lever B', (see Figs. l and 4,) with which it is connected by a rod CQ the said bell-crank lever being provided with a tappet D', arranged to engage an armb b D d on the pawl d, and the said tappet being arranged so as to enable it to move in a plane at right angles to the arm d' of the pawl. By reason of this construction when the iinger A is lifted by a tappet oli' the pattern- IOO IIO

chain" the lever B will be rockedA in the direction indicated by arrowin Fig. 4, andits tappet D', moving at the side of and engaging the arm el of'pawl'd,will"raise said pawl out of engagement with the ratchet-wheel b, and thereby prevent the 'transmission of motion from th'ecrank cto the ratchet b and renderr the shaft Zand the pattern-chain idle. It will be readily seen from this that the arm d of pawl d forms a stop-motion device.

'As` best shown in Fig.- 4, the rod C takes loosely throughan opening in the lower arm of the 'bell-'crank lever B and is provided below `the same with a threaded portion.` Above the lower arm of said lever B the rod O is provided with a collar C2, and below said'arm'on its threaded portion the rod is 'providedwith a nut C3, between which and the arm of lever B is interposed a coiled spring C4. This construction enables the rod Oto move the lever B in the direction of the arrow in Fig. et when the finger A' is raised and yet permits of the said lever B being moved in a direction opposite vto that indicated by the arrow without the movement of the rod C.

` Aresumption of the rotation ofthe pattern'- chain shaftI is effected at the-proper time through the medium of the following agency:

E" (see Fig. 5) is a wheel connected by gearing with the cloth-roll Hand having one or morevlateral lugs ee7 and an adjustable lat- Gr' is a rod connecting the other arm of the lever F' and an arm H' on the bell-crank lever B'. When the gear-wheel E is rotated by`the "cloth-roll Hv and interposed gearing is rocked, as before described. When the lever B is rocked in the direction opposite to,

that indicated byarrowfinFig. 4, it moves with respect to rod C and releases the pawl d, and thereby effects the resumption of movement of the pattern-chain. Such movement of the pattern-chain carries the tappet that raised and held the finger A' in its raised position out of engagement with said finger and enables the same and the rod C to resume their normal positions. The lug e2 of the wheel E is arranged in a curvilinear slot e3 in the wheel between the fixed lugs e e7 and is 'adjustably secured in position by a nut e5. From this it follows that the lug 'e2 may, when desired, be adj usted with respect to the lugs e and el.

The fingers ZS are designed, as stated, to be simultaneously raised by tappets of the pattern-chain, the finger Z being shown as raised and the finger S as depressed in Fig.

F is a lever having onearm ar-v ranged to be engaged by the said lugs, Iand'y l simply to illustrate'the'connection of the rod T to said finger S.

The general operation of the'machine is asV follows: The loom is started with a tappet on the pattern-chain below the'finger A', and

thereby the pattern-chainr is at rest. The lingers Z S S are in their'lower positions, andl as a result the-loom will weave plain-#that is; one pick to ea'chshed--until after the lug 6 7 engages and rocksthe lever F. Whenthe lever F' is rocked by thejlug e7, a' resumption of movement of the pattern-chain `will be" effected through the'medium ofthe mechanism described, and after the pattern is set in'm-V tion tappets arranged on a common barof the pattern-chain will simultaneously engage andA v raise the fingers Z 1S, and thereby'stop the `taking up of cloth and suspend movement'of' the harness and enable the loom to weave a `number of' picks-four picks for instance-in :one shed. This will put in a lcord effect.

After the tappets on a common barof the lchain pass out of engagement"y with the fingers' Z S tappets arrangedfon alternate bars' of theI vchain in the same plane as thefiinger S will come into play, and in consequence the loom will be caused to weave two picks in one shed and one pick in one shed alternately. This 4will put in a stripe or tapey effect. The putting in of the stripe 'or tape effectwill be fol-- vlowed by the iingers ZS being again 'raised y by two tappets on a common bar of the pat-r tern-chain to put ina second cord eifect. The

putting in of the said second cord effect will ICO be followed by the finger A being engagedv` and raised by a tappet of the pattern, and in consequence of this movement of the pattern 'will be suspended and the loom caused to The plain weaving will con weave plain.

tinue until the lever Fis rocked by the lu'g v e2 of wheel E and until the fingers Z S are A raised by tappets on a common bar of the pat`` tern-chain, when the operation'described will signs, the said designs" being separated by.V

e2 being adjustable itfollows that the first" n 'A' cord eect of the second design may be Aput in midway between the second'cord eectof the first design and the first cord of the third design or may be put in at a point nearerto the second cord effect of the iirst design than to the first cord effect of the third design," or

vice versa, as desired. i

We do not desire to be understood as co`nfinin g ourselves to the three lu gsj on the wheel E', as the number of Ylugs may be increased or diminished -at pleasure.' Wealso-do not wish to be understoodas coni'ni'ng ourselves to the use of an adjustable lug, although we prefer to employ the same for the reason stated.

It will be appreciated that by reason of our improvements the loom is enabled to put corded or tape effects in goods woven in one color quite as well as those looms which embrace fancy heads and drop-boxes. It will also be appreciated that our improvements when embraced in a plain loom do not affect the ordinary running of the loom, and therefore our improved loom is materially advantageous as compared with looms having dropboxes, because the lifting of the boxes adds greatly to the power required to drive the loom and the necessary instantaneous movement of said boxes causes severe shocks. An expert weaver is not required to run ourimproved loom, as all the pattern-chains are made and placed in the loom by the designer and do not require any manipulation until it is desired to change the design,
